We hiked up to Beaver Lake, and it wasn't too bad. I would say it's a little more strenuous than moderate, but not technical or difficult. The trail follows beaver creek all the way up, and the views are fantastic. It's pretty much straight trail up about 1,700 feet of elevation and about 3 miles each way. You get to the lake and it's like something out of a movie, just a picture perfect alpine lake. It's so clear you can see the trout feeding on bugs very clearly. It's a cool thing to do one morning.
